It seems that both data adapters are supported by the same instance of lightstreamer-adapter library, and this generates the issue.
Please could you confirm that you run the two Data Adapters in the same nodejs process? If this is the case, could you split the two data adapters in separate processes?

Yes, I run both of it in one nodejs process.
I have just tested your solution it's works fine!
Is this issue unpossible to add this opportunity to lightstreamer-adapter library (run few data adapters in one process) ?
